A Quick Guide to Servicing Your Vehicle’s Transmission

The fluid in your car’s transmission should be replaced every 30,000 miles. Over time, the assembly’s friction creates an enormous amount of internal heat. That causes the fluid to oxidize and lose its ability to lubricate the moving parts. Eventually, the lack of lubrication will cause the operational temperature to rise further, leading to varnish, cracked seals, and a loss in pressure. If your transmission fails, you can expect a hefty repair bill.

Below, I’ll quickly take you through the steps involved with changing your car’s transmission fluid and filter (it’s recommended that you do both at the same time). You can pay a mechanic to do the job, but you’ll save time and money by doing it yourself.

Draining The Fluid

If your car has an automatic transmission, it will also have a service pan that contains both the fluid and the filter. On the pan’s underside, there will normally a plug. Remove it and drain the fluid into a catch container. If the pan does not have a plug, you can drain the fluid when you remove the entire pan. Read the story →

Understanding What Can Go Wrong With Your Auto Transmission

We all know that there is no shortage of things that can go wrong with a vehicle but one of the more common things and probably the most concerning things is when something goes wrong with the auto transmission. The concern here is that it is not easily repairable and repairs are usually quite expensive and finally the car really just will not be able to function when the problems with the transmission are there.

There are signs that you are going to notice that there are transmission problems lurking. To begin with the car just may not feel like it is operating like it normally does. Then you may find that even when the car is not moving or is moving at a slow rate the engine is racing very fast. You may find that when you go to change gears it seems to be a very rough move rather than a smooth transition. It may seem like your changes have not even engaged or they have been missed. Sometimes you will hear unusual noises when you go to do your gear changes or even while you are driving. You may find that oil leaks or you may even get a burnt smelling odor off the auto transmission oil and it may even look black. Read the story →

Mercedes 126 Repair – Transmission Service

The transmission in the Mercedes 126 is a very robust design, as one would expect. In its day, it was one of the best units available, which led Porsche to use it in the legendary 928. But as with all other systems on these cars, we should not let the reputation for longevity stop us from performing frequent services.

As a general rule of thumb, transmission fluid should be changed every 30,000 miles. Unlike modern cars, where the trend is to do away with service access ports altogether, these Mercedes transmissions allow us to drain not just the pan but also the torque converter. In other words, we can remove almost the entire fluid charge without resorting to such gimmicks as power flushes.

Whereas engine oil should be changed hot, transmission fluid is best changed when merely warm to protect the mechanic from a very real risk of scalding. Read the story →
